BlackRock and Fidelity are quietly turning bitcoin ETFs into a two-firm market
BlackRock’s IBIT and Fidelity’s FBTC are attracting the vast majority of new bitcoin ETF money, leaving smaller funds increasingly sidelined as institutional investors consolidate around the industry’s largest players.
What to know:
- BlackRock’s iShares Bitcoin Trust and Fidelity’s Wise Origin Bitcoin Fund now dominate U.S. spot bitcoin ETFs, regularly capturing the majority of new inflows.
- Despite a roughly 29% year-to-date decline in bitcoin and waves of ETF redemptions, IBIT and FBTC have often acted as stabilizing forces, attracting capital even when rivals see outflows.
- The market is shifting toward a winner-take-most structure in which scale, liquidity and distribution networks favor BlackRock and Fidelity, leaving smaller issuers with minimal influence on overall flows.
Eighteen months later, the battle increasingly looks like a two-player race.
Data shows that BlackRock’s iShares Bitcoin Trust (IBIT) and Fidelity’s Wise Origin Bitcoin Fund (FBTC) are doing most of the heavy lifting when it comes to attracting new institutional capital, while smaller funds have become largely irrelevant in determining the direction of the overall market.
The trend was evident throughout the first half of 2026.
On January 14, bitcoin ETFs recorded net inflows of $840.6 million, according to data from Farside Investors. IBIT alone accounted for $648.4 million of that total, while FBTC added another $125.4 million. Together, the two funds represented more than 90% of all inflows that day.
A similar pattern appeared on April 17, when total inflows reached $663.9 million. IBIT brought in $284 million and FBTC added $163.4 million, accounting for roughly two-thirds of all new money entering the sector.
